First, a little brain chemistry 101: Melatonin is a hormone responsible for controlling basic biological functions, including body temperature and sleep cycles.
Little is known about their basic biological functions, including life cycle, since no species can be cultured continuously outside the mammalian lung.
Iron is fundamental to many basic biological functions including oxygen transport, production of adenosine triphosphate (ATP), DNA synthesis, mitochondrial function and protection of cells from oxidative damage.
Examples of basic biological functions include cellular metabolic processes, nucleic acid metabolism, and translation [ 28– 30].
Ranking these terms in order of statistical significance (Table 1) revealed that in the spleen, biological functions including lysosome, phagosome, cell adhesion, and basic metabolic function (carbohydrate, amino sugar, and nucleotide sugar) were most significantly impacted.
TRPV2 has been implicated in many biological functions, including somatosensation, osmosensation and innate immunity.
Bile acids have many biological functions, including biomarkers for liver function, signaling molecules with hormone-like functions and biomarkers for gut microbiota.
Chemokines, a family of structurally-related cytokine molecules, exert diverse biological functions including control of angiogenesis.
The genes affected help to govern broad and important biological functions, including stress, the immune system, inflammation, metabolism, and circadian rhythms.
Although the genes governing such basic biological functions as organ and blood development seem to be the same in both species, mice have far more genes involved in the sense of smell, sexual reproduction and immunity against pathogens.
This picture was simplified dramatically when it became apparent that all of these pathways could be linked to three basic biological functions: maintenance of the cell envelope, energy production and processing of genetic information.
